Answer:
A = 2x² + x - 45
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × breadth , thus
A = (2x - 9)(x + 5) ← expand using FOIL
= 2x² + 10x - 9x - 45 ← collect like terms
= 2x² + x - 45

A brick wall will be shaped like a rectangular prism. The wall needs to be 3ft tall and the builders have enough bricks for the wall to have a volume of 330 cubic feet. What tool can be used to find possible dimensions for the base of the wall?
Answers
Answer:
For a rectangular prism that has a base area B, and a height H, the volume is:
V = B*H
This is the only "tool" that we need to use in this situation.
We know that the wall needs to be 3ft tall, then H = 3ft
And we also know that we have enough bricks for a wall of a volume:
V = 330 ft^3
If we replace these two in the volume equation, we get:
330ft^3 = B*3ft
Now we can solve this for B, and thus find the volume of the base of the wall.
To do it, we just need to divide both sides by 3ft
(330 ft^3)/3ft = B*3ft/3ft
110 ft^2 = B
This means that the area of the base is 110ft^2
As the base is a rectangle of width W and length L, we must have:
110ft^2 = B = L*W
Then the possible measures of the base are given by the linear relation:
L = 110ft^2/W
Where we also need to add some trivial restrictions, like:
L > 0 ft
W > 0ft
This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.

Find the area of the triangle.
Answers
Answer:
66cm²
Step-by-step explanation:
The figure shown is actually a parallelogram
The area of a parallelogram can easily be calculated by multiplying the base length by the height
For this parallelogram the height given is 6 cm and the base length given is 11cm
so area = 6 * 11
6 * 11 = 66
hence the area of the parallelogram is 66cm²

The product of two consecutive even numbers is 224. What are these two numbers?
Answers
Answer:
14 and 16
Step-by-step explanation:
They are the ONLY consecutive even numbers
And also
x and (x+2)
x(x+2)=224 ( product of a number and the consecutive of that number)
x ²+ 2x-224=0
(x+16)(x-14) =0
x=-16 or 14
In this case 14 and (14+2) 14 and 16
The integers are either 14 and 16 or -14 and -16.

a+b=8
3a - 45=3
And is it good for the elimination method
Answers
Answer: a is 16, b is -8
Step-by-step explanation:
3a-45=3
add 45 to both sides to get rid of -45
3a=48
divide both sides by 3
a = 16
plug 16 into the first equation
16 + b = 8
subtract 16 from both sides
b = -8
is it good for the elimination method? hmm i probably wouldn't use it in this case since there aren't any variables to cancel out.

The required pairs of coordinates are [tex]\left[\begin{array}{ccc}1&1&-3\\-1&2&2\end{array}\right][/tex]
What changes happened when rotate 90° counter clockwise ?If we rotate a triangle 90° counter clockwise about the origin,
Then if one of its vertices be (x, y), it will be changed to (-y, x).
What is the required rotated vertex ?After rotating the given triangle 90° counter-clockwise about the origin,
The vertex (-1, -1) becomes (1, -1)
The vertex (2, -1) becomes (1, 2)
So, the vertex (2, 3) will be (-3, 2)
∴ The required rotated vertices are [tex]\left[\begin{array}{ccc}1&1&-3\\-1&2&2\end{array}\right][/tex]
